Epidural pain 4 months pp?

Okay, I just had my 5th baby and my first epidural. I didn’t have any really negative side effects, other than just being sensitive to the medication and it kept making my blood pressure drop. Well, I’ve noticed when I move a certain way I have a little pain in my spine, right where the epidural was. It’s not super painful, just kind of weird. I’ve tried putting pressure on the area and it doesn’t really hurt when touched, just when I move my back a certain way. I’ll definitely ask my midwife if it lasts for a long time, or gets worse. I’m mostly just curious if anyone has ever experienced this.
